IMPROVEMENT IN THE MANUFACTURE OF PAPER.

-wpeciication forming part of Letters Patent No. 57,192, dated August14, 1866.

To all whom 'it may concern:

Be it known that I, WILLIAM A. RUSSELL, of Lawrence, in the county ofEssex and State ot' Massachusetts, have invented an ImprovedlvIanufacture ot' Paper, to be used for the fabrication of papercollars, for cards, either plain or printed, and for any purpose forwhich the paper, when manufactured, may be used; and I do herebydeclarethe same to be fully described in thefollowing specification, andrepresented in the accompanying' drawing, which exhibits a section of asheet'ot paper as made with superficial and body layers in accordancewith my improvement.

In carrying out my invention I apply to a web or body of a coarse,cheap, and strong paper, such as is usually made from Manila hemp,Manila rope, Sisal grass, jute, or gunnybagging, either in its naturalcolor or bleached, two superficial layers of paper, such as is usuallymade from linen or cotton, or a mixture ot' the two, of a finer andwhiter character than the body of the sheet, and I make the applicationofthe superficial web to the opposite sides of the body of the web whenthese are in a plastic or adhesive state-that is, such a state as willenable them, when run together between rollers, to be compressed andbrought into one sheet by the pressure of such rollers. The three websare to be run between the rollers and are to be compressed together bythem, so as to make but one sheet. The superficial layers are to enablethe surface of the paper to take a high lnish or gloss, and to bewritten or printed onor stamped, or glazed, or embossed Without the bodylayer being visible.

In the drawing' a represents the body sheet, and b b the supercial orfiner sheets.

Paper of this kind may be made by handpressure or by a three-cylinderpaper-making machine, in which case there would have to be a separatevat for the pulp for the production of the body ofthe sheet.

I am aware that it is not new to run together and between rollers two ormore sheets of paper ot' the same quality or material or composition.Therefore I do not claim such.

What I claim as my invention is- The improved fabric or manufacture ofpaper as composed of a coarse, stronger, and more opaque material (suchas Manila hemp or Manila rope, Sisal grass, jute, or gunny-bagging) andtwo superficial or finishing layers ot' a ner and whiter material, (suchas linen or cotton, or a mixture of both,) applied, arranged, andcombined together under 'circumstances and in manner as hereinbeforeexplained.

WILLIAM A. RUSSELL.
